There's a discussion somewhere about this. it's a known issue if you have had a third party launcher installed at some time. it probablt happened if you uninstalled a launcher while the launcher was still active. you have to deactivate or exit the launcher then uninstall it. so just download a launcher enable it, disable it, then uninstall & it should clear it up. or there may be some utility to do this from zlauncher or other launchers.
